The amount of force impacted during a motor vehicle accident is much greater than Le Fort took into consideration during his work in the late 19th century. Treatment[edit]. A retrospective study on epidemiology and treatment of maxillofacial fractures. In reality, the Le Fort classification is an oversimplification of maxillary fractures. The key component of these fractures, in addition to pterygoid plate involvement, is involvement of the lateral bony margin of the nasal opening. Such a fracture has a pyramidal shape and extends from the nasal bridge at or below the nasofrontal suture through the frontal processes of the maxilla, inferolaterally through the lacrimal bones and inferior orbital floor and rim through or near the inferior orbital foramen, and inferiorly through the anterior wall of the maxillary sinus; it then travels under the zygoma, across the pterygomaxillary fissure, and through the pterygoid plates. The so-called dish-face or pan-face deformity may occur after an extensive Le Fort II or Le Fort III fracture. Previous Next Indications Extensive maxillary fractures are usually associated with significant cosmetic and functional sequelae.

Unlike with fractures in other bones, muscle forces do not play a significant role in the final position of the broken bony segments.
